This month's "Column Watch" takes us to HPLC '99 in Grenada, Spain. Ron Majors describes some of the more interesting paper and poster presentations and new developments and technologies in columns, sample preparation, and genetic research.
LCGC 17(10), 900–907 (1999)Extracting Estrogenic Hormones Using Rotating Disk and Modified Clays
April 14th 2025University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).
